It’s hard to think anyone could ever upstage Amanda Bynes (pre-rehab) when it comes to public dissing and humiliation on Twitter. These celebrities, however, sadly provide us with some solid entertainment thanks to their ridiculous tweets and give Miss Bynes a serious run for her money.

Heartbroken singers, Justin Bieber and John Mayer, are trying to win their exes back. While Mayer keeps telling all his (and her) friends he wants Katy Perry back, Bieber is taking to Instagram to woo Selena Gomez with song.

Fans were shocked to learn that Katy Perry and John Mayer split (what’s up with all our favorite couples having trouble?) but new details have put things into perspective. The on and off couple has had trouble in the past, but Mayer won Perry back with the promise of being a better boyfriend. He initially made good on his promise and even wanted to marry her. However, she wasn’t ready for that kind of commitment especially given Russell Brand.

The holidays often call for “ugly” sweaters (or as the English politely put it, “Christmas jumpers”) and matching outfits with your siblings. It’s a season of festive garb you’ll likely regret years later, yet not one that excludes our favorite celebrities.

The romance between Katy Perry and John Mayer is heating up and insiders predict she may have a new reason to ROAR. Marianne Garvey tells The Gossip Table that Mayer is meeting with designers to pick out a ring. If all goes according to plan, the two could be engaged by Thanksgiving. Talk about a romantic holiday!

Getting fit takes hard work, determination, and apparently… a really flustered facial expression.

Check out the full gallery of all 25 stars below!

Looks like Chris Brown may have gotten himself into some more trouble. Delaina Dixon tells us that the singer allegedly got physical with a woman while partying at a club. Following a performance in Orange County, Brown went clubbing with some friends. It was when he was leaving that he was accused of pushing a woman out of his way. The woman ended up in the hospital to treat injuries to her leg.

Brown’s camp denied any involvement in the situation but the police confirmed that the woman did file a report. However, it’s an active investigation and no one has been charged.

From Daenerys’ platinum tresses to Khal Drogo’s foxy eyeshadow, we’re obsessed with each Game of Thrones character’s signature look (so ripe for Comic Con costuming!). They seem so unique, but here’s the thing — outside the mythical borders of Westeros exist real-life people who look exactly like them. Exactly.

Which hottie from The Host is officially off the market? How did Ryan Gosling become a motorcycle maniac for The Place Beyond The Pines? And in sadder news, the cast of the Harry Potter films says goodbye to one of their own. All this in today’s First Dibs.

The Grammys are usually a night to dig deep into your wardrobe and bust out your very best for the cameras! Well, apparently some peeps didn’t get that part of the memo. While many A-listers strutted their stuff on the red carpet in their high fashion finery, there were folks who appeared to have lost a bet or something.
